There is no crashlog in crash-reports

Extra
Game fails to launch entirely, log provides very little info. Crash exists in heavy modpacks as well as with running dependencies only, removing either mod allows the game to launch as normal.

Fixed for the next release - you may try this build to have it working until then.
